Fuzzy Extractors: How to Generate Strong Keys from Biometrics and Other Noisy Data

4 Feb 2006Yevgeniy DodisRafail OstrovskyLeonid ReyzinAdam Smith

We provide formal definitions and efficient secure techniques for - turning noisy information into keys usable for any cryptographic application, and, in particular, - reliably and securely authenticating biometric data. Our techniques apply not just to biometric information, but to any keying material that, unlike traditional cryptographic keys, is (1) not reproducible precisely and (2) not distributed uniformly...
